【Application】For many years, bismaleimide (BMI) has been used as a resin material to make heat-resistant structural parts and high-grade electrical insulation materials because it can withstand high temperatures and has good strength. It is used in industries such as aviation, aerospace, power equipment, electronics, computers, communications, trains, and construction. The main uses include:

1. Electrical insulation materials for motors

• High-temperature resistant insulating varnishes (with solvent and solvent-free types)

• Enamel wire coatings

• Laminated insulating boards

• Non-woven binding tapes

• Mica insulating tapes

• Copper-clad laminates for circuit boards

• Molded plastic parts

• High-temperature resistant powder coatings (F to H class) modified with epoxy resin

• Cast parts

  2. Matrix resins for advanced composite materials

• High-temperature structural parts used in aircraft and spacecraft

• High-temperature carbon fiber parts

• Printed circuit boards

• Other functional materials

  3. Engineering plastics modification

• Used as reinforcing agents or crosslinking agents for various common plastics, such as PP, PA, ABS, APC, PVC, PBT, EPDM, PMMA, etc.

• Also used as a new type of rubber vulcanizing agent (a substance that makes rubber hard and strong)

  4. Wear-resistant materials

• Diamond grinding wheels

• Heavy-duty grinding wheels

• Brake pads

• High-temperature resistant bearing adhesives

• Magnetic materials

  5. Other areas

• Oil-free lubricating parts in fertilizer production (ammonia synthesis) equipment

• Dynamic and static sealing materials

• It is also used in many other high-tech fields.
